Basic safety information Note Elements / Components sensitive to electrostatic discharges This device contains electronic components sensitive to electrostatic discharges. They can get damaged if they are touched by an electrostatically charged person or object. In the worst case scenario, these components are instantly destroyed or go out of order as soon as they are activated. To minimise or even avoid all damage due to an electrostatic discharge, take all the precautions described in the EN 100 015-1 norm. Also ensure that you do not touch any of the live electrical components. The transmitter type 8222 was developed with due consideration given to accepted safety rules and is state-of-the-art. However, risks may arise. Failure to observe these instructions as well as any unauthorised work on the device excludes us from any liability and also nullifies the warranty which covers the device and its accessories. 9

Description 5. 5.1. Description Area of application The 8202 transmitter is intended solely for the measurement of the conductivity. Thanks to 2 fully programmable transistor outputs, the transmitter can be used to switch a solenoid valve, activate an alarm and, thanks to 1 or 2 4-20 ma current outputs, establish one or two control loops. 5.2. 5.2.1. General description Construction The 8222 transmitter comprises: a sensor for measuring physical parameters, comprising: -- 2 electrodes measuring an impedance in Ohms -- a Pt1000 temperature sensor measuring a resistance. an acquisition / conversion module for the physical parameters measured: -- acquisition of the impedance measured in Ohms -- conversion of the impedance measured into conductivity units -- acquisition of the resistance measured and conversion into temperature a display module with browse button used to read and/or configure the parameters of the device. The display module is available as an accessory. One version of the 8222 transmitter with 2 transistor outputs and a 4-20 ma outlet operates on a 2-wire system and requires a power supply of 14-36 VDC. For such a version, electrical connection is done via an M12, 5-point, male fixed connector. One version of the 8222 transmitter with 2 transistor outputs and 2 4-20 ma outlets operates on a 3-wire system and requires a power supply of 12-36 VDC. For such a version, electrical connection is done via an M12, 5-point male fixed connector and an M12, 5-point female fixed connector. 5.2.2. Conductivity sensor The 8222 transmitter is fitted with a sensor measuring the conductivity. The sensor is fitted to the electronic module using a pin and cannot be dismantled. The sensor itself comprises a Pt1000 temperature sensor and 2 electrodes (in stainless steel for sensors with a C constant of 0.01 or 0.1, in graphite for sensors with a C constant of 1.0). The conductivity of a fluid is the capacity of this fluid to conduct electrical current thanks to the ions in the fluid. An alternating voltage is applied to the electrode terminals: the current measured is directly proportional to the conductivity of the solution. 11

Adjustment and functions 10.8.3. Calibrate the sensor (menu Sensor - function "Probe") Refer to paragraphs 10.5 and 10.6 to access the Calib menu. CALIBRATION: Calibrate the conductivity sensor by determining its specific C constant. See details next page. A calibration process updates the last calibration date ("Last cal. date" function of the CALIB INTERVAL sub-menu hereafter). Sensor Probe Temperature Probe Calibration Cell constant Calib interval Probe Cell constant Calib interval Teach special This calibration can be replaced by the C constant input for the sensor in the "Cell constant" function below. Entering the cell constant does not update the last calibration date ("Last cal. date" function of the CALIB INTERVAL sub-menu hereafter). CELL CONSTANT: Read the last C constant determined by the Calibration function above or modify it. This input replaces a calibration made by the "Calibration" function above but does not update the last calibration date ("Last cal. date" function of the CALIB INTERVAL sub-menu hereafter). CALIB INTERVAL: Read the date of the last calibration (function "Last cal. date") and programme the periodicity of calibrations, in days (function "Interval"): the transmitter generates a "maintenance" event by displaying the icon and a "warning" event, each time a calibration is due. Set function "Interval" to "0000 days" to ignore the function. The "warning" event may be associated with one or other or both transistor outputs (see 10.7.5). See also "If you encounter problems" at 11.3. TEACH SPECIAL: Define the temperature compensation graph specific to your process. The graph thus determined and memorised is used by the transmitter when you choose "Special" in the "Comp." function in the menu "Param - Sensor" (see 10.7.6). See details page 51. 48
